我正在尝试使用mysql 5.5.31 (社区版)进行行压缩,以避免在仓库类型的上下文中进行反规范化时出现以下错误。
ERROR 1118 (42000): Row size too large. The maximum row size for the used
table type, not counting BLOBs, is 65535. You have to change some columns
to TEXT or BLOBs我启用了各种系统变量,如下所示:
mysql> show variables like 'innodb_file%';
+--------------------------+-----------+
| Variable_name | Value |
+--------------------------+-----------+
| innodb_file_format | Barracuda |
| innodb_file_format_check | ON |
| innodb_file_format_max | Barracuda |
| innodb_file_per_table | ON |
+--------------------------+-----------+但是,当我尝试执行以下测试时,我仍然得到相同的行大小太大的错误。
create table foo ( first varchar(10000),
second varchar(10000),
third varchar(10000),
fourth varchar(10000),
fifth varchar(10000),
sixth varchar(10000),
seventh varchar(10000)
) ENGINE=InnoDB ROW_FORMAT=Compressed KEY_BLOCK_SIZE=8;有人知道我可能会错过什么吗?有几个来源表明这应该是可行的。

尝试将varhcar(x)改为text或blob,它在我的测试中运行良好:
create table foo_text (
first longtext,
second longtext,
third longtext,
fourth longtext,
fifth longtext,
sixth longtext,
seventh longtext
) ENGINE=InnoDB ROW_FORMAT=Compressed KEY_BLOCK_SIZE=8;https://stackoverflow.com/questions/20352835
